A boundary integral equation method for the solution of a class of two-dimensional elasticity problems involving multiple interacting cracks in an elastic material is presented. The method is used to obtain a procedure for the numerical evaluation of the crack tip stress intensity factors for this c

## Abstract This paper presents a triangular finite element for the solution of two‐dimensional field problems in orthotropic media. The element has nine degrees of freedom, these being the potential and its two derivatives at each node. The ‘stiffness’ matrix is derived analytically so that no fu
The fluid-dynamical equations governing wave propagation in catalytic converter elements containing isothermal mean flow are linearized, approximated and written in appropriate forms to act as the basis for a finite element solution scheme involving time harmonic variation. This solution scheme is d
